T0 @ZZ whom t nza/y concern;

Beit known that I, PERLEY R. GLASS, of Quincy, county of Norfolk, and State of Massachusetts, have invented an Improvement in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the. drawings representing like parts.

The present invention relates to an eyeleting-machine, and is embodied in a machine for setting eyelets, rivets, and the like, especially eyelets, the machine being mainly intended for work on leather stock, especially shoe-uppers. In a machine of this class it is necessary in order to obtain good results to employ a tubular punch coperating with a l fiat anvil, since no other kind of a punch will properly cut holes in leather or retain its cutting edge when used with this material for any length of time.

It is the object of the present invention to simplify the construction of the machine, so as to obtain the greatest possible rapidity c and efficiency, and to this end the machine embodying the invention is provided with a reciprocating tubular punch having an annular clenching-iiange from which it projects, so as to combine in one tool a punch and setting device which is adapted first to punch the material and then to coperate with another reciprocating setting device adapted to pick up an eyelet and present the same to the clenching portion of the punch, thus insert-` ing the eyelet in the previously-punched hole and setting or clenching the same.

In machines as heretofore commonly constructed, in which a tubular punch adapted tooperate properly upon leather stock has been employed, it has been found necessary to utilize a pair of setting devices, both operated independently of the punch itself. In accordance with the present invention, however, this multiplicity of tools is dispensed l tion of the punch will readily enter the eyelet to prevent the cutting edge from injuring or being injured by the edge of the eyelet. To insure, therefore, that the eyelet will be properly guided into the hole or opening in the stock, the machine is provided with means independent of the punch and anvil, or coperatingpunching devices, as they maybe called, for forcing the punch through the material after the actual punching or cutting operation is completed, so that the said punch will project beyond the surface of the material before the eyelet is presented thereto. It is desirable, moreover, that the outer surface of the tubular punching projection should be tapered somewhat, so thatv as the said punch is forced through the material the hole therein will be slightly enlarged, while the tapering projection will engage the edge of the eyelet as the punch projects into the same and guide the said edge between the exterior of the y punch and the material surrounding the same.

In this way the eyelet presented by the independent setting device is properly guided and positioned, and a slight inaccuracy in the original positioning of the eyelet on the setting device will not result in 'crushing the eyelet or damaging the punch, as would be the case if a similar imperfection existed in a machine which did not have a tapered punch or a machine in which the diameter of the punch was as nearly as possible equal to the interior diameter ofthe eyelet, so that the hole originally punched might be as nearly equal as possible in diameter to the diameter of the eyelet itself.

The' invention further relates to noveldetails of construction and arrangement, which Will be more fully described hereinafter.

Figure 1 is a front elevation of a machine embodying the invention; Fig. 2, a vertical section of the same; Fig. 3, a detail in section on the line Q03 of Fig. 2; Fig. 4, a similar detail in section on the line 0c of Fig. 2; Fig.

`5, a section on planes transverse to that of Fig. 2, the upper portion of said section being taken on a line at the rear of the punchframe and the lower portion being taken on a line farther back and just in front of the feed-operating cam; and Figs. 6, 7, S, and 9 are enlarged sectional details of the combined punch and setting-tool and the coperating setting device, together with a portion of the feed-table, to illustrate the successive ICO steps in the operation, especially with a view to showing the manner of inserting and clenching the eyelet. Y

The machine embodying the invention com prises the tubular punch a, shown as externally tapered and provided with the annular clenching-surface a2, the coperatin g setting device l), shown as provided with a spring- Iinger b2, and the eyelet-feed chute c, adapted to receive eyelets from the hopper c2 and to be moved into and out of the path of the seting device o in the usual way, so as to successively present the eyelets to the linger o2 prior to the setting operation. The punch a, cooperates in the punching operation with a suitable anvil or support for the material, the punch and anvil thus constituting cooperating punching members, the said anvil A being indicated in Fig. G, in which the punch is shown in the position assumed at the end of the punching operation. It is necessary, therefore, prior to the setting operation that a movement of one of the said punching members relative t0 the other should take place in order to permit the setting device l) to move toward the clenching-surface a2 and cooperate therewith in the setting operation.

As herein shown, the punch d is arranged to have a lateral movement, the same lateral movement which brings the punch into a position to be met by the setting device also serving to feed the material after the same has been punched. To this end the punch is mounted in a laterally-movable frame a3, shown as capable of sliding on the guide-rod c, supported in lugs B, formed in the front part of the frame of the machine. The punch is capable of a reciprocatingr longitudinal movement within said frame, as will be hereinafter described, so as to perform the actual punching operation, but is moved with the frame between successive punching operations, so as to feed the matcrial and cooperate in completing the setting or clenching of the eyelet.

To produce the lateral movement of the frame a3, the said frame is connected, in accordance with the present invention, with an oscillating member d, provided with a radial arm d2, which arm is connected by a universal joint with the punch-frame a3, so as to compensate for the difference between the curved and rectilinear movements of the two parts. As herein shown, the said arm d2 is provided with a channel d3, the walls of which engage a sliding block of, pivotally connected with the frame a3, the said block being herein shown as held in position with relation to said frame by means ot' a screw u, having a rounded head di, which constitutes a bearing for the said block. In the oscillation of the said member d, therefore, the punch-frame will be laterally reciprocated, it being essential that the said punch-frame should come to rest at one end of its reciprocating movement in such a position that the punch will be in line with the setting device b in order to cooperate there- A within setting the eyelet. The member (l is oscillated in response to the rotation of the main shaft of the machine, as will be described, and the arm d2 is shown as adjustably connected to said member, so that the exact position of the punch at the end of its feed movement may be properly arranged for. As herein shown, the said arm d2 is provided with a hub or collar d3", having ears or lugs d, each of which contains an adj Listing-screw d5, which cooperates with a tongue or projection d from the member d. The distance between the lugs d4 is somewhat greater than the thickness of the tongue d, so that b y turning one or the other of the screws the position of the arm relative to the member (l may be determined, as best shown in Fig. 3.

In the construction shown the lateral movement of the punch is utilized to feed the material so as to produce a completely automatic setting operation, the punch first descending to cut the material, then moving laterally to transfer the same to the setting device, and then returning to punch anotheropening prior to the next setting operation. It is desirable, however, to provide the machine with means for varying the extent of the feed movement in case it is necessary to set part of the eyelets at one distance apart and other eyelets inv the same line at dierent distances apart.

This is accomplished by varying the lateral or feed movement of the punch, and in accordance with the present invention the member d, which is shown as a sleeve having a bearing on the'shaf t @,which produces the vertical reciprocating lnovement of the punch, is provided with an arm (Z7, projecting radially from said member and being connected with an actuating member (ZS, which receives a reciprocating movement from a cam (Z9 on the main shaft C of the machine, which is adapted to be continually rotated during the operation of the machine. The said cam (Z9 cooperates with engaging surfaces d, formed in a frame du, connected with the member d8, the said member also being provided with fingers or projections (Z13, Fig. 4, constituting a fork embracing the shaft C, so as to keep the frame (V2 in proper position with relation to the cam d. Thus while the movement of the member Z8 is mainlya reciprocating movement said member is tree to turn slightly with relation to the shaft C, so as to properly follow the movement of the arm (Z7, with which it is connected. Thus in the operation of the machine the rotation ofthe main shaft C through the action of the cam (Z9, the connecting member d3, and the arm d7 will oscillate the member d in accordance with the shape of the cam nl, so as to produce the necessary movement thereof to feed the material and return the punch to its normal position. It is obvious, however, that the extent of such movement will be varied by shifting the point of connection between the arm (Z7 and the con- IIO necting member d8 toward or from the axis of oscillation of the member cl, since the nearer the said point of connection is to the said axis the longer will be the movement of the said member d. In order that the point of connection may be thus shifted readily by the attendant even while the machine is in operation, the arm ds is shown as connected, by means of a link d, with an actuating device, shown as an elbow-lever d, pivoted at elle, one arm of said elbow-lever being connected at d with a suitable actuating device, such as a treadle. (Not herein shown.) Taking the parts, therefore, in the position shown in Fig. 5, if the point C117 is moved downward it is obvious thatv the connecting member d8 will be carried toward the axis of the member d, thereby lengthening the feed movement. The amount that the feed movement is lengthened may be determined by the stops dlg, one at each side of one arm of the elbow-lever CD5, the said stops being shown as screw-threaded in suitable lugs and held in position by locknuts d, so that they are easily adjustable to vary the extent of movement of the elbowlever and the consequent variation in the feed movement of the punch.

It is of course necessary that the punch should'always be arrested at the end of its feed movement in such position that it will be directly in line with the lower setting device, so as to receive the eyelet therefrom and cooperate therewith in the setting operation. To this end the member d8 is connected with the arm dl by means of a stud d8, arranged to engage the walls of a slot d in the member C17, and the said walls of the said slot d70 are curved upon the arc of a`circle struck from the axis of the shaft C when the said arm Z7 is in such a position that the punch is directly in line with the lower set. It is obvious, therefore, that no matter to what position the stud also is shifted there will be no variation in the position of the punch at this point of its travel, so that no matter what the feed movement may be the said punch will always be arrested in the proper position with relation to the setting device. In other words, the extent of feed movement is varied by initially varying the extent of backward movement of the punch, so that said punch may be caused to engage the material at varying points on the punch-block, while it always moves said material to such a position that the punched hole is in line with the lower set, which is laterally stationary. The extent of feed movement, therefore, is equal to the distance between the point where the material is punched and the point where the eyelet is set, and the said distance is variable in accordance with the variation in the initial rear movement of the punch.

The reciprocating movement of the punch is produced, as has been stated, through the agency of the shaft e, which is arranged to be continuously rotated, and is provided with a cam e2, which coperates with engaging surfaces e3, formed in a block e4, which is connected with the punch a. As shown, the said surfaces e3 constitute an elongated channel, so that the block is capable of movement along the cam to permit the lateral movement of the punch, and is also adapted to be moved to reciprocate the punch in response to the rotation of the said cam. As best shown in Fig. 1, the shape of the cam is such as to permit the punch to dwell at the end of its movement toward the anvil, so as to remain in this position until after the setting operation is completed.

The shaft e is herein shownr as rotated by means of a pair of eccentrics e5, each of which has an eccentric-strap e connected by a rod e7 with an eccentric-strap es upon an eccentric e9, mounted on the shaft C. The two eccentrics on the same shaft are set so that one is about a quarter of a turn in advance of the other in order that one pair of eccentricstraps will be in operative position when the other pair are on the dead-center.

Since there must be a lateral movement of one of the cooperating punching members relative to the other prior to the setting operation in order that the combined punch and setting-tool and the other setting-tool may come together, it is necessary that the punch and anvil, which are forced into firm engagement with each other in the punching operation, should be freed from each other in order that the lateral movement of one of the said parts may take place freely and Without friction, since otherwise both the punch and the anvil would be rapidly worn out and the machine would not operate properly. As herein shown, the anvil A is so arranged as to have a slight movement away from the punch immediately after the punching operation, the said anvil being shown as pivoted at A2 and supported upon an eccentric A3,which is arranged to be rotatedin any suitable or usual way, as by beveled gears A4, A5, A, and A7, the lastnamed gear being upon the main driving-shaft C. The operation is clearly indicated in Figs. 6, 7, S, and 9, Fig. 6 showing the position of the anvil at the end of the punching operation and the other figures the position of the anvil immediately after the punching operation is completed, but prior to the movement which takes place in order to permit the punch and setting device to come together. The slight downward movement of the anvil prior to the lateral feed movement of the punch separates the cooperating punching members, so that the lateral movement may be freely accomplished, it being obvious, however, that the parts may be so timed that these movements may begin almost simultaneously, thereby insuring great rapidity of operation.. It will be seen, however, from Fig. 6 that at the end of the punching operation the cutting edge of the punch is on a level with the lower surface of the material and that it does not project beyond the surface of the material at all. It is desirable,

however, that the punch should be somewhat smaller than the edge of the eyelet which is to be set in order to obviate all liability that the edge of t-he punch and the edge of the eyelet may come in contact with each other, and thereby injure or destroy one or both, and in any event prevent the proper setting of the eyelet in that particular hole. lVith the punch smaller than the eyelet, however, and flush with the surface of the material the eyelet instead of entering the opening in the material would come in contact with the uncut material around the punch if the material were allowed to remain in the position shown in Fig. G during the setting operation. To insure the proper setting, therefore, and to assist in guiding the eyelet into the opening, the machine is provided with means for forcing the punch completely through the material until it projects beyond the surface of the same after the punching operation is completed and prior to the setting operation. .As herein shown, this is accomplished by providing the anvil A or any suitable portion of the feed-table with projecting fingers AS. (Shown on a large scale in Figs. G, 7, 8, and 9.) These fingers project upward beyond the end of the punch, one at each side thereof, as the said punch travels laterally from the position shown in Fig. (5 to the position shown in Figs. S and 9. The material carried along by the punch, therefore, will come in contact with the upper surfaces of the fingers A3 and will be forced upward onto the punch, as shown in Fig. 7, so that when the said punch is in the position to coperate with the setting device it will project wholly through the material and beyond the lower su rfaee of the same. This is best shown in Fig. 8, in which it will be seen that the punch projects into the eyelet E until the edge of the eyelet engages the tapered walls of` the punch and is thereby guided into the hole made in the material, which is enlarged sufficiently to properly receive the eyelet, so that the said eyelet cannot fail to enter and be upset or clenched, as shown in Fig. 9.

It is obvious that the means for forcing the punch through the material after the punching operation may be readily modified, and it is not intended, therefore, to limit the invention to the particular means herein shown and described.

The lower set b is carried by a vertical reciprocating rod b3, adapted to be reci procated by means of a wrist-pin C2 upon a disk C3, formed upon the main shaft C. The said wrist-pin C2 enters an opening in a block ZJ, capable of sliding in a cross-head b5, suitably connected with the rod b3, so as to produce a regularreciprocating movement of the setting devceb. Thesaidsettingdevicebisvertically adjustable with relation to the rod b3 by means of a screw-threaded adjusting member 6G, which bears against the end of a shell 117, which in turn engages the end portion of the set ZJ, the upper portion of said set being engaged by an annular cap or nut bs. In adjusting the set the nut bsis turned to such a position as to determine the proper position of the set, and the adjusting member b is then screwed up until the parts are locked, as will be easily understood by reference to Fig. 2.

The finger b2 is acted upon by a spring L, contained in the shell D7. The said finger, which is adapted to pick up an eyelet from the chute c in the usual way, is tapered, so as not to come in contact with the edge of the punch, and will usually be depressed by contact with the piece of leather last punched out of the material.

To retain the material in position after the setting operation has taken place and prior to the return movement of the punch, the machine is provided with a gripper memberf, spring-pressed against the feed table or anvil, as shown, and connected with a verticallymovable rod f2, acted upon by an arm fg, pivoted at f4 and operated by a cam f5 on the shaft C. The parts are so timed that the gripper descends and engages the material just after the feed movement is completed and remains in engagement therewith as the punch and setting device move apart. To enable the operator to insert the material prior to starting the machine, the gripper'member is also arranged to be acted upon by a lever fo, connected with a suitable treadle or actuating device. (Not shown.)

The feed-chute c may be reciprocated or IOO oscillated in any suitable or usual way to present the eyelets to the setting device and is herein shown as oscillated by means of a cam c3, acting on the forked extremity c" of an elbow-lever c5, suitably connected with an oscillating frame which carries the Said eyeletchute and feed-hopper, the construction and arrangement of which need not be further described, since they form no part of the present invention.

It is to be understood that while the punch has been hereinbefore described as laterally movable, constituting also the feed member of the machine, such a construction is not cssential to the invention, since other means for feeding the material may be employed, while it is obvious that other means might also be employed for laterally separating the punch and anvil to permit the setting device to come in line with the said punch.

It is further obvious that many other modiiications might be made in the specific construction and arrangement of the machine, and it is not intended, therefore, to limit the invention to the particularembodiment thereof which has been herein shown and described.
